By gildegoma:

in other builders (ruby.rb, php.rb,... ), file existence is done with

```
shell.file_exists?(foo)
```

Is it so only because of shell stub in spec ? Actually I tried to switch to shell.file_exists trying to fix my failing build, but without any success. see http://travis-ci.org/#!/gildegoma/travis-build/builds/407582
